Samuel James Cassell Sr. is an American professional basketball coach and former point guard who serves as an assistant coach for the Boston Celtics of the National Basketball Association (NBA). Drafted 24th overall in the 1993 NBA draft out of Florida State, Cassell played for eight different teams during his 15-year career. He was selected to the NBA All-Star Game and All-NBA Team once, both in the 2003–04 season.

The 1993 NBA draft took place on June 30, 1993, at The Palace of Auburn Hills in Auburn Hills, Michigan. The draft had some talented players at the top, but injuries and personal problems hurt many of them. Chris Webber, Penny Hardaway, Allan Houston, and Jamal Mashburn were All-Stars whose careers were cut short by injuries. Isaiah Rider and Vin Baker showed great potential but were plagued by personal problems. Bobby Hurley's career was derailed by a car wreck in December of his rookie year. The mid-to-late first round was littered with players that failed to make any significant impact, with the exception of three-time NBA champion Sam Cassell. One of the NBA best all-time wing defensive players, three-time champion Bruce Bowen, went undrafted.
